Get good at managing time...
You have a lot of spare time, and you have far too many things to fill them with.
I am not a TV person, but even one hour a day occupies 5 - 6 hours in the working week that could be used for other stuff.
When traveling, get an iPod. Use the travel time to learn via audio books from Audible.com.
Get up half an hour earlier, leave work an hour sooner.
Take lunch at the desk and make sure to always make time to work out.
There are many many ways to save time, but the best way is by not wasting it. At my time in life (30 - 40 with small kids, a career, books to write and everything else...) every bit of time I can find I put to best use.
